$$What forecasters said that day
The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Atlanta, GA wrote its last area forecast discussion before this special weather statement went out at Aug 11, 3:08 PM EDT, 3 hours 21 minutes earlier.
Area forecast discussion, Aug 11, 3:08 PM EDT, 3 hours 21 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 308 PM EDT Fri Aug 11 2017 .SHORT TERM /Tonight through Saturday Night/... Afternoon showers and thunderstorms are certainly more robust over the far eastern CWA, but even still, thunderstorms are more isolated in nature. Tropical air mass still in place, and as upper level wave moves through the area Saturday, have kept pops above average, with likely across the majority of the area Saturday afternoon. The surface front is expected to move to stall over middle Georgia by early Sunday. At this time we have opted to cancel the Flash Flood Watch that had previously been in effect through 2 AM Saturday. The currently expected rainfall amounts are under 0.5" across the area. Early convection over eastern Georgia has been producing 1 to 2 inches, but the scattered showers developing over western Georgia this afternoon have been lacking the same punch, producing only a quarter inch or so per hour, if that. As the Flash Flood Watch was for a large portion of NW Georgia, we have canceled it. The risk of flash flooding based on the radar trends and the short term models is isolated. We do, however, remain in a tropical air mass with PWs near 2.0 inches. With no clear steering flow today, slow moving and training storms can still drop a quick couple inches. While flash flooding is not likely, please stay alert to changing conditions. Have generally gone with a blend of model guidance for temperatures. Although some clearing is possible tonight, expect mostly cloudy conditions again Saturday and into Sunday.31 .LONG TERM /Sunday through Friday/... No major changes to the long term. The CWA remains in a wet pattern with mainly afternoon and evening showers and thunderstorms through next weekend. Previous Long Term Discussion follows... 17 LONG TERM /Saturday Night through Thursday/... A wet pattern continues through much of the extended periods. The upper level flow will remain out of the southwest with weak waves moving through the flow across the forecast area, with weak surface boundaries as well. A good short wave moves across the area mid week. POPs will continue in the chance to likely range during afternoon heating, although anticipate some breaks in the showers and thunderstorms each day. The lack of upper level dynamics will keep the chance for severe storms low, however scattered strong to isolated severe storms with locally heavy rainfall cannot be ruled out. Guidance temperatures look on track with near normal lows for this time of year. Given the abundance of moisture and expected cloud cover afternoon highs should run just below normal through the period. Atwell .AVIATION... 18Z Update... Generally high MVFR to VFR across the area this afternoon. Expect clouds to degrade to generally MVFR before sunrise, with patchy IFR. Best TS chances will be through 20-22z, with just generally VCSH appropriate through early evening. SW winds will shift to the W-WSW by mid morning Saturday. Speeds will be light overnight, then increase to 5-7kt after 14z. Have included a PROB30 for 18-22z Saturday for possible TSRA. //ATL Confidence...18Z Update...
